Build an Arduino heart rate monitor with a MAX30102 sensor and a 16x2 LCD.

Create a burglar-tripwire with the ultrasonic sensor.

This project will show you how to use temperature and hmidity (DHT11 and DHT22) sensors with an Arduino card.

Read data from an absolute orientation sensor without writing any code!

Periodically measure environmental conditions and send them to WolkAbout IoT Platform to monitor the environment remotely.

As the title says, this is a pretty simple PIR motion controlled relay using an Arduino Nano.

During the summers, many people get sunstroke because of playing in the sun for too long. So this device will prevent getting sunstroke.

Use the DHT Temperature Sensors in C# code via a C++ Windows Runtime Component to implement a one-wire protocol on Windows 10 and the RPI2.

In this protip, I will show you how to build DS18B20 Digital Thermometer with Arduino.

In this tutorial, we will learn how to detect Smoke and inflammable gases using an MQ-2 sensor.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

Generates maps based on distance between itself and obstacles autonomously and provides visual feedback.

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

Did you know that a standard three-wire PC Fan can be used as a sensor?

Short and easy, read distance 2 - 400 cm and plot it in I2C OLED screen.

Read temperature and humidity values in a remote location and store the data in an SD card.

Uses an accelerometer to level a platform.

We are showing how to use DS18B20 one wire water proof temperature sensor using Arduino.

Tracks compass heading, altitude, temperature, pressure, humidity, time, travel distance and GPS location during a hike.

With only an arduino board, two servos, and an hc-sr04, and some python, you can create a room scanner that is capable of showing depth!

This is the first version of my Arduino Weather Station, a very simple project that will give you weather information.

Arduino is used with MQ-135 to determine the air quality and then this value is updated to ThingSpeak channel.

Use an Arduino, two small servo motors with light sensing photo resistors to steer a solar panel towards the sun. UPDATED

A simple Electromagnetic Field Detector.
